How do I URL-escape a string in Rails?

<% redirect_href = "/redirect?#{CGI.escape target}&foo=bar&baz=some_other_stuff" -%><a href="<%= redirect_href =>">Foo</a>

ruby-on-rails url escaping

Rails (activesupport) defines Hash#to_param (aliased to Hash#to_query):

 {foo: 'asd asdf', bar: '"<#$dfs'}.to_param # => "bar=%22%3C%23%24dfs&foo=asd+asdf"

It's worth noting that it sorts query keys (for HTTP caching).

Hash#to_param also accepts optional namespace parameter:

{name: 'David', nationality: 'Danish'}.to_param('user')# => "user[name]=David&user[nationality]=Danish"

ruby-on-rails url escaping

can be used from anywhere, part of ruby std lib.
